jamis,
Thanks! I wasn't totally clear about the second question. Say I have
400 hosts, and I only want to run something on 5 at a time, instead of
all of them. Can I restrict to operating in batches? A good use case
example is a set of web servers that have dependencies on each others
deploys and need to having 'rolling' deploys. While I know this could
be done by placing them in different roles, it wouldd be tedious to do
it with all 400 if all I really want is to batch the execution.
